Infinite loop while using Event as test in while loop

Help and Feedback Scripting Support
#1

I have this piece of code

while hammer.Unequipped do

wait()
print("Hammer is unequipped")

end

The loop is not ending when the hammer is equipped. Why does this happen?

#2

Tool.Unequipped is an event that is always in a Tool instance. While loops pass if the statement isn’t falsey or nil. Try using a boolean to signify if the tool is equipped or unequipped.

Unequipped is an event, so it will always be truthy. (its a userdata, and only false and nil are falsy)
If you want to check if it is unequipped, using both Equipped and Unequipped should work.

local IsEquipped = false
hammer.Equipped:Connect(function()
    IsEquipped = true
end)
hammer.Unequipped:Connect(function()
    IsEquipped = false
end)
while not IsEquipped do
    wait()
    print("Hammer is unequipped")
end

Depending on what you’re doing, this could be done differently. For example, if this is a player’s tool, you could simply check if the tool was a descendant of the player’s character.
